5IO BIRDS OF THE REPUBLIC OF PANAMA PART 3 



Panama on Cerro Campana and at the base of Cerro Chame. East 

 through the Canal Zone they occurred along the Rio Pacora, at La 

 Jagua, in the scrub forest near the Rio Bayano at Chepo, and near 

 Chiman. The most eastern records are from near Chiman and the 

 head of tidewater on the Rio Maje. 



On the Caribbean slope Arce's records include Calovevora, and I 

 found them on the Rio Indio at El Uracillo on the upper reaches in 

 northern Code and at Chilar, lower down in western Colon. In the 

 northern Canal Zone, the type of the race was taken near Lion Hill 

 by McLeannan. It is reported on Barro Colorado Island and else- 

 where at Juan Mina, and near Gatun. Near Mandinga, in western 

 San Bias, they ranged in the undergrowth in swampy woodland. The 

 call is a low sibilant note, not audible except near at hand. 



Skutch (Pac. Coast Avif., No. 34, 1960, pp. 496-506) writes of 

 the nest of the closely allied race T. s. cinereiceps in Costa Rica, that 

 it is built by the female alone. He describes it as a rounded structure, 

 swinging freely from a slender, leafy twig of a tree or vine, built of 

 slender black vegetable fibers, bound together by cobweb. He writes 

 that it "resembles a chemist's retort, hung so that the tubular neck is 

 vertical or nearly so and its opening points toward the ground." 

 Carriker (Ann. Carnegie Mus., vol. 6, 1910, p. 725) described the 

 eggs as "creamy- white, with a slightly rufous tinge, speckled, chiefly 

 about the larger end, with cinnamon-rufous." Two eggs are laid. 

 Measurements are 21 X 14 and 20.5 X 14 mm. 



Skutch described the newly hatched young as dark skinned without 

 down. The male assists in care of the young, which are fed insects, 

 and occasionally berries. Females are recorded sleeping in the nest 

 before the eggs are laid, and continuing to use it but alone for a 

 period after the young leave. Later, like the male, she sleeps in the 

 open without shelter. 



Article 32(c) of the International Code of Zoological Nomencla- 

 ture in its second section rules that a name published originally with 

 a hyphen "is to be corrected by the deletion of the mark." The sub- 

 specific term flavo-olivaceus of the present species is unusual in its 

 formation, and one awkwardly written without the hyphen. It is noted 

 that Article 26(c) provides for this separation where a Latin letter 

 is used. The present case may be justification for an additional 

 exception in the use of a hyphen.
